  Abstract

  Background: obesity is directly related to dyslipidemia which contributes significantly

  to the risk of coronary heart disease, a major cardiovascular disease and a serious

  health problem. The aim of this study was to compare the effects of low calorie

  diet and those of lovastatin on serum lipoproteins, apo B, homocysteine, and total antioxidant capacity (TAC) in hyperlipidemic obese patients.

  Methods: In a randomized clinical trial, 41 obese patients were stratified by BMI,

  serum triglyceride (TG) and total cholesterol (TC) and randomly allocated to one of

  these groups: 1- Lovastatin tablet (40mg) 2-1200 calorie diet per day according to the

  therapeutic lifestyle change (TLC) dietary pattern for 8 weeks. Serum lipoprotein,

  apo B, homocysteine, and TAC were measured enzymatically, immunoturbidometrically,

  via EIA , and colorimetrically respectively.

  Results: There were a significant decrease in mean of the serum TC (P=0.0001),

  LDL- c(p=0.0001), TG/HDL-c(p=0.03), apoB (p=0.0001) and significant increase

  in TAC (p=0.0001) in diet group at the end of the study compare to lovastatin group.

  TC, LDL-c, TG, LDL-c/HDL-c , TC/HDL-c , TG/HDL-c, homocysteine and apo B

  showed significant decrease but TAC showed significant increase in the diet group at

  the end of the study compared to beginning values (p=0.0001, p=0.0001, p=0.0001,

  p=0.001, p=0.0001, p=0.0001, p=0.0001, p=0.0001 and p=0.002, respectively). But

  in the lovastatin group only TC, LDL-C, TG, LDL-c/HDL-c, TC/HDL-c and apo B

  had significant decrease at the end of the study compared to beginning values

  (P=0.0001, P=0.0001, P=0.0001, P=0.01, P=0.02, P=0.002, respectively)

  Conclusion: The study revealed that when compared to levostation 1200 kcal diet

  according to TLC dietary pattern had more beneficial effects on serum lipoproteins,

  apo B, homocysteine and TAC, so it may decrease CVD risk factors and mortality

  in hyperlipidemic obese patients.
